Is the circuit wiring between the motor starter in a motor control center going to the equipment disconnect with a circuit breaker in it a feeder or a branch circuit?

The terminology for a feeder is any wire that is coming into a device (it feeds the device with power). A feeder will be the wire coming into the disconnect and also the wires going into the motor will be called feeders. Even the wires coming into the MCC will be termed feeders. Branch circuits are circuits that usually originates at the main distribution and spread outward to their respective loads. Branch circuit terminology encompasses all of the equipment in the circuit that is connected from the overload device to the field load device.

What does the trip free characteristic of a circuit breaker mean?
A trip free circuit breaker is one that will disconnect a circuit even if the manual switch is held at the "on" position. It is a safety feature to prevent a circuit breaker being disabled either deliberately or accidentally.
What protects equipment from too much current by tripping a switch that breaks the circuit and stops the flow of electricity?
Circuit Breaker
What would cause circuit breaker to trip in new box from old box?
A circuit breaker will trip if it is faulty or if the connected circuit has a short circuit or a connected device is trying to draw more current than the breaker rating. If you disconnect the output wire from the breaker and it still trips, it is a faulty breaker. If the breaker is tripping immediately when it is turned on then start disconnecting elements of the circuit to see what might be causing the problem. If everything was working and now isn't, it is likely that the wire from the breaker is nicked where it exits the box and is shorting to the feedthru connector.
What will cause a new circuit breaker to trip out continually and not reset when moved to the off position?
A short straight to ground. Unplug and disconnect everything from the circuit and then reconnect things one at a time until the breaker trips. That is your problem. (Also could be a bad breaker)
Will a ceiling fan work if it's not grounded?
Yes, the grounding of equipment is for safety reasons not operational reasons. By grounding equipment, the conductor, if the equipment develops a short circuit to ground, supplies a low impedance return to the distribution panel where is is sensed by the circuits breaker. Once the breaker senses this short circuit current it will trip the circuit open.
What is a non auto circuit breaker?
A non-auto circuit breaker is a circuit breaker with the trip element removed. Basically, it is a modified circuit breaker that is now a disconnect switch (glorified disconnect switch).
What is the difference between disconnect switch and circuit breaker?
A circuit breaker is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow.The term switchgear, used in association with the electric power system, or grid, refers to the combination of electrical disconnects, fuses and/or circuit breakers used to isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream.
What Type of equipment of circuit breaker?
Well from my experience , i know that the equipment used for testing is called, Electroclysis Differentiator with a Dicasidace Robinium resistor.

Can you use a circuit breaker as a mean of disconnect?
Yes, but I would not recommend it if you are constantly turning the power on/off. If that is the case install a disconnect.
What is the range of circuit breaker that can be used for a 24V DC equipment?
Use a fuse
Why supply circuit breaker should be 4poles?
Because it has neutral with 3 phases. A supply circuit breaker is used on the lv side of the transformer to protect the equipment connecting to it.
What does a fuse or circuit breaker do when too much electricity flows through a circuit?
A fuse or circuit breakers purpose in a circuit is to disconnect the circuit load from the voltage source when a circuit fault occurs.
Why 630 amps load breaker switch is used in ht line?
A circuit breaker is necessary to protect the equipment from faults.
How do you know if the AC breaker matches the AC unit starting demand load?
Read the literature for the ac condensing unit, or the tag on the outside of the unit. Minimum circuit ampacity= minimum breaker, wire and fuse size. Maximum circuit ampacity= the maximum size. Your circuit breaker, wire size and disconnect fuses should all be at or between those 2 numbers.
